Resource Planning Model
The National Renewable Energy Laboratory's Resource Planning Model (RPM) is a capacity expansion model designed for a regional power system, such as a utility service territory, state, or balancing authority. It is an optimization model that finds the least-cost investment and dispatch solution over a 20-year horizon. The investment decisions are made for multiple conventional and renewable generation technologies, storage technologies, and transmission. The model has high spatial resolution down to the individual unit and with multiple solar and wind spatial resource regions. Dispatch modeling within RPM is conducted on an hourly time-step sampled throughout a year and considers energy balance, reserves, and many generator constraints. Transmission dispatch is represented with a linearized DC power flow algorithm. A simplified representation of the rest of the interconnection for which the region of interest resides is included in the model to account for boundary interactions. We designed RPM specifically to consider the characteristics of wind and solar technologies, particularly location-dependence, variability, and uncertainty, in its investment decisions. For example, distance-based interconnections, changing capacity credit, increased operating reserves, curtailment, and cycling costs are considered by the model.
